Port issue when using Flask app with mod_wsgi

Question

I have deployed a Flask app(REST API) on Apache server. The Apache server is part of the WAMP setup. Its a windows 10 machine. When I run the flask app using flask server, I can bind it to any port and it works. But when I try to use it from mod_wsgi, I get the error

OSError: [WinError 10013] An attempt was made to access a socket in a way forbidden by its access permissions

Apache is running on port no 5000. I was expecting flask app to use the same port and execute the python code. What am I doing wrong.

In the virtual host config is given below

<VirtualHost *:5000>
DocumentRoot "${INSTALL_DIR}/www/AppDir/"
Alias /CourseReco/ "${INSTALL_DIR}/www/AppDir/"
<Directory "${INSTALL_DIR}/www/AppDir/">
    Allow from all
    Require all granted
    Options Indexes Includes ExecCGI FollowSymLinks
    AllowOverride None
    Order deny,allow
    DirectoryIndex index.cgi index.html index.py
    AddHandler cgi-script .py
</Directory>

The app_API.wsgi file is

#!d:/development/anaconda/envs/app_api/python.exe
import sys

import logging

logging.basicConfig(stream=sys.stderr)
sys.path.insert(0,"C:\wamp64\www\AppDir")

from app_API import app as application

The app_API.py file looks like this. The answer from this question has been used to instantiate another class

Object Oriented Python with Flask Server?

from flask import Flask, jsonify, request
from apilogic import apilogic
import logging
logging.basicConfig(filename='example.log',level=logging.DEBUG)
import os
class app_API:
    applogic= apilogic() #I want to load data once and not for every API call so doing this

from flask import Flask, jsonify, request
app = Flask(__name__)

@app.route("/getData")
def GetData():
    input=request.args.get('arg1')
    return app_API().applogic.send_data(input)

if __name__ == "__main__":
    app.run()

What is it that I am doing wrong? Any help is appreciated. Thanks
